Overview

The device clearly uses a Texas Instruments SoC, but it is not easily discernible from the FCC internal photos. It may be a DM3730 (DaVinci Video Processor).

"Rev: 1.0" and "2052500285" is silkscreened on the wireless module. A label with a MAC address on the device indicates the OUI is 6C:FD:B9.

This is clearly a TP-LINK module, rebranded by Proware (TP-LINK was once a Shenzhen Proware Electronics brand (old TP-LINK site on archive.org), but now the TP-LINK brand seems to have become the primary designation for the company).

Specifically, the model is a Proware PW-MN427.

A later model appears to use a PESI module. (FCC ID: YZZGXV3175-P)

The board has silkscreened text near the USB connectors (probably) indicating the maximum provided per connector. The upper connector is marked as 300mA. The lower connector (closest to the SD Card slot) is marked as 700mA.

From the manual..
